Description
We present an analysis of the $N \pi$ contribution to the determination of the nucleon mass spectrum using constrained fits. Our study involves simultaneous fitting of $N \to N$ and $N \to N \pi$ correlation functions. The analysis is performed on a $24^3 \times 48 \times 24$ lattice with $2 + 1$ dynamical Domain-Wall fermions. We employ a lattice spacing of $a^{-1} = 1.74 \text{ GeV}$ and a pion mass of $m_{\pi} = 279 \text{ MeV}$. Further, we will discuss our preliminary results for the computation of the nucleon axial charge.
